Vitamin D and MS

Healthy Origins D3 5000 IUCaucasians, especially those of Northern European descent, are more likely to get MS than any other ethnicity. Most of the people with MS lived above the equator. Could it be that the proposed hypothesis that the lack of Vitamin D is the cause, or a great contributor to MS is accurate?

If so, are we getting enough Vitamin D? How much is enough?

The findings were presented at the annual meeting of the American Academy of Neurology, “In contrast to many vitamins, no recommended dietary allowance (RDA) has been established for vitamin D.

Instead, the Institute of Medicine has set a so-called adequate intake level; the recommendations are 200 IU daily for people under 50, 400 IU daily for people 50 to 70, and 600 IU for those over 70.”

John Hooge, MD, an MS specialist at the University of British Columbia in Vancouver, says he recommends MS patients take at least 1,000 IU and “probably 2,000 IU” every day.

Health.USNews in an awesome resourse to learn about health issues. Of course we need to talk with our doctor to decide, but being the information era, there is much to learn online. Health USNews confirms that many patients quite reasonably prefer to start with a 1,000 unit capsule of vitamin D3 every day.

  1. Hello Linda,

    I found my way here by way of comments for this post on your other blog: – very helpful information, by the way – thank you!!

    I’ve always wanted to understand MS more myself just out of my passion for nutrition. I also have a cousin living with MS, though fortunately she has been able to function fairly well. She finds that stress will cause hers to flair up quite a bit, which makes sense.

    I had to comment here, because I am particularly very passionate about educating people of the extreme importance of optimal vitamin D levels!
    I have a natural health website (you can find it listed under ‘My Favorites’ via my blog link below) and have written several articles about vitamin D.

    My personal experience is this: I live in Indiana, so we do not get the right kind of sunshine for producing vitamin D for nearly 8 months of the year. During this time, we will use up our vitamin D stores – if we have any! My level was 20.6 ng/mL last February – deficient, as I expected! I began vitamin D3 (drops in olive oil) right away for 8 weeks. I had been prescribed a vitamin D by the Dr to be 50,000IU/week. Unfortunately, the prescription was for vitamin D2, which I knew would not be effective! So with the drops (2000IU/each drop!), I took 3 drops one day (6000IU), 4 drops the next (8000IU). When I was re-tested 8 weeks later, my level was 47.4 ng/mL, I have been maintaining with a dose of 5000IU/day and will be re-tested in the next 8 weeks. My goal is to get my level to 80-90 ng/mL, which is recommended by some experts.

    There is a chart you’ll find interesting posted on my natural health website – the Disease Incidence Prevention Chart’ from By the way, this is a great website – this and others are referenced on my vitamin D page.

    I hope this helps! I believe that anyone with MS should discuss this with their physician!

    • Beth,
      I’m glad you found my blog! I’m happy for your cousin~ MS affects everyone differently! Hopefully she’ll be one of the few who never have serious symptoms! I am very interested in your knowledge! I look forward to reading your blog and learning from you!!

  2. I have a good friend with MS and will pass this information on to her. I also find Dr. Mercola’s information interesting as well. He is another big proponent of vitamin d supplementation and often recommends extremely high doses, such as 5,000 IU per day. It’s always important that people remember to talk to their doctor about supplements.

    • Anthony,
      I agree, especially in the northern climates, we need to take large doses! I encourage all my kids but especially my pregnant daughters to take a bunch!

  3. I has read somewhere that vitamin D-3 4000 IU a day for adults is best for your immune system also which I’ve been taking for the last 6 months. I usually get 2-3 sinus infections a year and have not gotten sick at all so far this winter.

    • Isabella,
      Isn’t it amazing, supplements are crucial! Our food simply doesn’t have everything we need and if we don’t live in a sunshine state, and often if we do! I think it’s exciting that you are recognizing benefits from vitamin D!
